On my Dad’s old OMC 17 foot dual deluxe he added a balance tach. If the needle was centered running both motors were running at the same RPM. If one was working harder the needle would show off to either side & was time to balance the mtrs.
A noteworthy and interesting comment. Actually, you can tell by sound if they are running different RPMs. That drives some people nuts. Me, it doesn’t bother me that much, Close is good enough for me. In fact, I sort of like the sound. Except two RD-14s sure will be loud.
